New Delhi, July 4 Late King of Pop Michael Jackson, who died of a suspected cardiac arrest last week, had reportedly employed a "day team and night team" of nannies to look after his eldest son Prince Michael.

The 'Thriller' sensation was said to be desperate to ensure that Prince Michael was properly cared for after his birth in 1997, and thus hired 12 people so that someone would always be with his son, reports the China Daily.

"The baby was cared for by a team of six nannies and six nurses, who worked in shifts so that there were always two nurses and two nannies by his side," a source who worked at Michael's Neverland Ranch said.

"They were kept under constant video surveillance, which was monitored by members of Jackson's security team. The nannies all had special training.

"The day-team did exercise drills with the baby to build up his strength. The night-team read and sang to him," the source added.

Concerned about his child's well-being, adds the newspaper report, Jackson even ordered the nannies to throw away the boy's toys each evening to guard against germs.

A nanny revealed: "We had to measure the air quality in his room once an hour. When we fed him, all the utensils had to be boiled and were all thrown away after a single use."

Prince Michael was the singer's first child with his ex-wife Debbie Rowe. (ANI)
